The brain weighs just over a kilo. The brain contains about 100 billion cells. The brain uses 20% of the body's energy. The brain sends messages in the same way as a computer works. There are more possible connections in your brain than there are atoms in the universe.）（ There are different areas in the brain which are responsible for different functions. We now know which parts of the brain are related to different parts of our body and feelings from them. The brain also has different areas for different kinds of thinking. you have one area for your first language and another area for a foreign language that you learn when you are older.）
